Tell us what’s happening:

Can someone please help me as to why my code is wrong?

Pretty sure I am checking while the next node is none, assigning the next node to current. If you think there is an error with my logic in the condition, please point that out so that I can figure out the criteria

Your code so far

class LinkedList:
    class Node:
        def __init__(self, element):
            self.element = element
            self.next = None
            
    def __init__(self):
        self.length = 0
        self.head = None

    def is_empty(self):
        return self.length == 0
    
    def add(self, element):
        node = self.Node(element)
        if self.is_empty():
            self.head = node

# User Editable Region

        else:
            current_node = self.head
            while not (current_node.next is None):
                current_node = current_node.next

# User Editable Region


my_list = LinkedList()
print(my_list.is_empty())

Your while loop should check that current_node.next is not None.

Ok I changeed the condition to current_node.next is not None and it worked. But how is this condition different?
